Description

Technical Field

[0001] The utility model relates to the technical field of composite conductor multi-core electric wires and cables, in particular to a composite conductor multi-core electric wire and cable. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables.

[0003] For example, a composite conductor multi-core wire and cable with the authorization announcement number "CN219891915U" can protect the inner core through the insulating layer, the water-blocking layer can be waterproof and moisture-proof, and the wear-resistant layer increases its wear resistance. Through the contact between the isolation layer one and the isolation layer two, the inner core and the protective sleeve will not be melted due to high temperature, and there will be no hot melting bonding between the inner sheath and the insulating sleeve due to high temperature. This avoids the situation where the insulating sleeve of the inner core is broken and cannot be used again when the protective sleeve is subsequently removed to separate the inner core, thereby increasing the practicality of the cable. However, in the composite conductor multi-core wire and cable, it is sometimes necessary to arrange multiple wires at the same position, which will make multiple composite conductor multi-core wires and cables fit together, and it is easy to form multiple composite conductor multi-core wires and cables. The outer skins of the wires and cables rub against each other, shortening the service life of the composite conductor multi-core wire and cable, and increasing the danger of the composite conductor multi-core wire and cable. Utility Model Content

[0007] Preferably, the control structure comprises an outer sleeve and a straight tube, the inner wall of the outer sleeve is fixedly connected to the outer wall of the anti-puncture layer, the outer wall of the outer sleeve is fixedly connected to the inner wall of the straight tube, and the outer wall of the straight tube is fixedly connected with a plurality of arc plates.

[0008] Preferably, the inner diameter of the arc plate matches the diameter of the outer sleeve.

[0009] Preferably, a filler layer is fixedly connected to the inner wall of the inner sleeve.

[0010] Preferably, a plurality of wrapping layers are fixedly connected to the inner wall of the filler layer.

[0011] Preferably, a wire core is fixedly connected to the inner wall of the wrapping layer.

[0012] The utility model provides a composite conductor multi-core wire and cable, which has the following beneficial effects: other wires and cables are inserted into the interior of the arc plate through the control structure, the inserted wires and cables are clamped by the arc plate, and at the same time a certain gap is formed between the multiple wires and cables to avoid entanglement and friction between multiple wire and cable brackets, the outer wall of the straight tube sleeve supports the arc plate, thereby ensuring the service life of the composite conductor multi-core wire and cable and eliminating the danger of the composite conductor multi-core wire and cable.

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] Embodiment 1:

[0020] See also Figure 1-4 In the present embodiment, a composite conductor multi-core wire and cable comprises an anti-puncture layer 1 and an anti-seepage layer 3. The outer wall of the anti-puncture layer 1 is connected to a control structure 2. The anti-puncture layer 1 is made of a metal wire mesh. The inner wall of the anti-puncture layer 1 is fixedly connected to the outer wall of the anti-seepage layer 3. The anti-seepage layer 3 is made of cross-linked polyethylene. The inner wall of the anti-seepage layer 3 is fixedly connected to a pressure-resistant layer 4. The pressure-resistant layer 4 is made of polyvinyl chloride. The inner wall of the pressure-resistant layer 4 is fixedly connected to an insulating layer 5. The inner wall of the insulating layer 5 is fixedly connected to an inner sleeve 6. The insulating layer 5 and the inner sleeve 6 are both made of rubber.

[0021] The control structure 2 includes a jacket 201 and a straight tube 202. The inner wall of the jacket 201 is fixedly connected to the outer wall of the anti-puncture layer 1. The outer wall of the jacket 201 is fixedly connected to the inner wall of the straight tube 202. The straight tube 202 is a rubber tube fixed to the outer wall of the jacket 201. A plurality of arc plates 203 are fixedly connected to the outer wall of the straight tube 202. The inner diameter of the arc plate 203 matches the diameter of the jacket 201. The inner wall of the arc plate 203 can be clamped with the outer wall of other wires and cables.

[0022] By controlling the structure 2, other wires and cables are inserted into the arc plate 203, and the inserted wires and cables are clamped by the arc plate 203. At the same time, a certain gap is formed between the multiple wires and cables to avoid entanglement and friction between multiple wire and cable brackets. The straight tube 202 is sleeved on the outer wall of 201 to support the arc plate 203, thereby ensuring the service life of the composite conductor multi-core wire and cable and eliminating the danger of the composite conductor multi-core wire and cable.

[0023] A packing layer 7 is fixedly connected to the inner wall of the inner sleeve 6. The packing layer 7 is made of polyester yarn. A plurality of wrapping layers 8 are fixedly connected to the inner wall of the packing layer 7. The wrapping layers 8 are made of rubber. A wire core 9 is fixedly connected to the inner wall of the wrapping layer 8. The wire core 9 is made of copper.

[0024] Working principle:

[0025] When using the wire and cable, when the wire and cable are fitted and connected, other wires and cables are inserted into the arc plate 203, and the inserted wires and cables are clamped by the arc plate 203. At the same time, a certain gap is formed between the multiple wires and cables to prevent multiple wire and cable brackets from being entangled and forming friction. The straight tube 202 is sleeved on the outer wall of 201 to support the arc plate 203. The anti-puncture layer 1 on the inner wall of the outer jacket 201 can block sharp objects through its own metal wire mesh to avoid direct penetration of the wire and cable. The anti-seepage layer 3 on the inner wall of the anti-puncture layer 1 has waterproof properties through its own cross-linked polyethylene material, the pressure-resistant layer 4 on the inner wall of the anti-seepage layer 3 has pressure resistance through its own polyvinyl chloride, the insulating sleeve 5 on the inner wall of the pressure-resistant layer 4 has an insulating effect through its own rubber material, the inner sleeve 6 on the inner wall of the insulating sleeve 5 forms a double-layer thickened insulation through its own rubber material, and the filler layer 7 on the inner wall of the inner sleeve 6 can support the wire and cable through the polyester silk material.

[0026] Embodiment 2:

[0027] See also Figure 1-4 In this embodiment, a composite conductor multi-core wire and cable further includes an inner core 10, and the outer wall of the inner core 10 is in contact with the outer wall of the wrapping layer 8.

[0028] Working principle:

[0029] When the wire and cable are bent, the wire core 10 will be supported between the multiple wrapping layers 8, thereby preventing wear between the multiple wrapping layers 8.
